HSRP and BGP Backdoor

[Andy Guley]

I have two routers that have two seperate t1's.  Both routers connect to a MPLS network that talks back to the corporate office.  I have HSRP setup on both routers.  The routers are connected across the LAN and HSRP works fine.  I am only announcing the routes from each router.  I.E.  10.110.91.0 /24 is only announce from one router.  10.110.195.0 /24 is only announce from the other router.

When t1's fail at one site HSRP kicks and and fails over like it should.  However I cant get to the router that it failed over to from the corporate office until I announce both networks from the one router.  So the 10.110.91.0 /24 router is now announcing the 10.110.195.0 /24 network.  Can I use the BGP backdoor command on the 10.110.91.254 router to announce the 10.110.195.0/24 network? 

Or how can I get the network to be announced when the t1's fail?

Thanks

You could look at advertising both subnets from both routers and changing the Weight or Local preference so the next hop knows which route to prefer.
